This AWS project will update tasks, whenever a new Docker image push in ECR occurs

ecr-task-deployment

This project will create Lambda function that updates task, whenever we push new image into ECR.

Prerequisites

• AWS CLI - The AWS Command Line Interface (CLI)

Getting Started

We need to do this only once. If there is same stack already running on AWS, we do not need to do anything.

First time setup

Run make upload (this will create S3 bucket, if it does not already exist, upload CloudFormation template and Lambda function).

Go to AWS Console under CloudFormation, choose create stack and check last option (Specify an Amazon S3 template URL) under Choose a template. Paste a link form S3 bucket where the CloudFormation template.yaml was uploaded to. Proceed to the next step by clicking Next. Under stack name you can type something like EcrTaskDeployment. That's it.

Everything else should be created and set automatically.

This stack updates tasks on both development and production ECS cluster environments.

Explanation

If you have a development and production ECS clusters, this setup will update tasks on both ECS environments. One prerequisiteis needed, for this to be achievable. We need to tag our Docker images with either :development or :production tags.

As for lambda function goes, we need to pass CLUSTER_SUFFIX environment variable. So in case we have ECS cluster named development-ecs and production-ecs, we need to pass to lambda just ecs and it will be concatenated automatically.
